R-Meter MK III

he James Instruments R-Meter MK III represents
the re-birth of a classic rebar locator. It utilizes
Tthe latest in eddy current sensing and micro-
processor technology to accurately locate, determine
depth, and estimate diameter of metal objects in
concrete.
The eddy current sensor is specifically designed to
react to the outer surface of the metal object. It is
uninfluenced by small metal particles in the con-
crete, whether the concrete is fresh or hardened,
wet, or dry. The eddy current sensor also allows the
unit to locate both ferrous as well as non-ferrous
metals in concrete; thereby finding not only steel
reinforcing bars accurately, but tendons, copper tub-
ing, conduit, and more.
The latest in microprocessor technology not only
conditions the signal from the sensor for more accu-
rate and dependable results but provides the user
with the information they need. Rebar diameter can
be estimated by using a simple system of compari-
son all fully automated for consistent, repeatable
results with increased resolution over previous mod-
els. The microprocessor can also statistically ana-
lyze the data, searching automatically for minimum
cover points, and the least cover of a group of
points. Cover points can be displayed as a symbolic
map of a structure to assist the user in finding prob-
lematic areas. Built in memory can store over 80
thousand individual data points for processing.
The optional scan cart can be used to graphically
